Iguanodontia (ig-WAN-oh-DON-ti-ah) is a branch of Ornithopoda whose size
ranged from small-to-very large. This infraorder, encompassed such families
as Dryosauridae, the duck-billed Hadrosauridae, and of course, the Iguanodontidae.

Iguanodontidae (ig-wan-uh-DON-tih-day) is a family of ornithopods that
lived from the Late Jurassic to Late Cretaceous Periods. They could grow
15 feet - 20 feet (4.6 - 6.1 meters) long. Like all ornithopods, the iguanodontidae
were bipedal and herbivorous. Iguanodon, Ouranosaurus, Probactrosaurus,

The Ingeniinae (in-JEE-nee-nay) is a subfamily of Oviraptoridae. Unlike
several other members of the Oviraptoridae, they did not have crests, and
the claws on their second and third fingers were relatively small.
Intelligence of Dinosaurs
Traditionally, dinosaurs have been considered dim-witted creatures, but
recent thought is more generous. Evidence suggests that sauropods, which
do have rather small brains compared to their bulk, lived in herds and
cared for their young. This implies a level of intelligence greater than
that of most modern reptiles. Theropods have been found to have relatively
large brains with specialized structures, and this argues that they were
intelligent in the way that wolves and lions are intelligent.
